If the case is only male genitalia dissection for photography, I never use the mentioned method, but only put the tip of the abdomen into warm water for a minute or a few. This is not invasive to any other parts of the specimen (wings, pillosity, potentially dna etc.), of course as long as you are especially careful with "mechanics" and get this practiced.

Hi all,

Sometimes I need to relax flies to extract genitalia or to model them for photography. I use the method described in the attached paper, which works really well. Working with steam has one disadvantage though, the wings often wrinkle.
I heard there is a slower method to relax flies, which takes a day or so in which the wings do not wrinkle. Does anybody have experience with this and is happy to share this method?

Cheers,
Sander
